You view on timeline is too short. We're not talking about keeping something online for 7 years, but for 70. If I had followed your advice a few years ago, I would have deployed on Geocities. Do you know what happened to those websites?
The question is, is wordpress going to be around in 70 years? No one knows. But that static HTML page will still render fine, even if it is running in a backward compatibility mode on your neurolink interface.
The question isn't whether wordpress will be around in 70 years, but whether it will outlast your self-hosted website. Anything that is self-hosted requires significantly more financial/logistical maintenance, and what is the likelihood of someone continuing to do that for 70 years?
Also, in most cases even you would have a very hard time accessing them, unless you somehow "pinned" them not to be far far down the scroller.
It'll live forever...

Yes, from a technical pow, but what about deplatforming? I think it is a bigger risk to lose data than any framework/technology deprecation. I would definitely not rely on any platform keeping my data.
In comparison, the websites that I've built and hosted or deployed myself, have constantly required periodic work just to "keep the lights on". I went out of my way to make this as minimal and cheap as possible, but even then, it hasn't been nearly as simple as the content I've published on wordpress.
At some point, people's priorities change. Perhaps due to new additions to the family, medical circumstances, or even prolonged unemployment. And when that happens, even the smallest amount of upkeep, whether it is financial, technical or simply logistical, becomes something they have no interest in engaging with.
If we really want our content to last, not just for 10 years but for a generation, our best bet is to publish it on a platform like wordpress.com. One which requires literally zero maintenance, and where all tech infrastructure is completely abstracted away from you. I know this isn't going to be a popular idea with the HN crowd, and I do not blame anyone at all for wanting to keep control over their content. People are free to optimize along whatever dimensions they wish. But if I had to bet on longevity, I would bet every time on the wordpress article over the self-hosted one.
